Stuck on loading screen

Hi,

Whenever I try to start whatever mode on Brink (so campaign, free play, etc.), the game gets stuck on the loading screen. It worked a few months ago, but I didn't play it in a while, and when I tried to play it again, I made a new account, because my old one was gone. And now I can't play the game anymore. All my other games work fine on my PS3. Can someone please help me? I have patched it to version 1.04, because otherwise the game won't let me play.
